Abstract
The utility model relates to a protecting thread disassembling machine for a pipe, which is an apparatus for disassembling protecting threads on a pipe with screw threads. The utility model is especially suitable for disassembling protecting threads on a petroleum well entering pipe. The apparatus is composed of a base part, a drive part, a sliding platform part, a main shaft part, a thread disassembling part, etc., wherein the drive part uses fluid drive and pneumatic drive, so the utility model is safe and reliable. A thread disassembling head is convenient to replace to adapt the disassembly of the protecting thread of a male and a female buckles with different types on various pipes. Through the utility model, the mechanization operation of disassembling the protecting threads of pipes can be implemented, the intensity of labor can be reduced, and work efficiency can be enhanced.
Description
The utility model relates to and a kind ofly is used for the thread protector that the end is threaded and protects the tubing of the thread protector of screw thread, especially oil to go into the well casing material and unloads deduction, belongs to the standard machinery class.
At present, both at home and abroad for the dismounting of the thread protector of threaded tubing, generally all adopt the method for hand disassembly, labour intensity is big, efficient is low, especially in big production, and the manual operations of this simple tool, promptly heavy, dangerous again, seriously influence production efficiency and production management.
The purpose of this utility model provides a kind of tubing thread protector that can be used for the automatic dismounting of tubing internal and external threads thread protector mechanization and unloads deduction.
Tubing thread protector of the present utility model unloads deduction and is mainly graded by base portion, drive part, sliding platform part, main shaft portion and shackle head and form.Base portion comprises base and platform slideway etc., and the platform slideway is fixed on the base.Drive part comprises the leading screw fluid motor and drives leading screw that leading screw fluid motor and driving leading screw all are installed on the base.Sliding platform partly comprises platform, spindle carrier and sliding nut etc., spindle carrier is fixed on the platform, and sliding nut also is installed on the platform, when meshing with the driving leading screw, also be slidingly matched, accept from the power of drive part and rise and set upright guide effect with the platform slideway.Main shaft portion is made up of main shaft, reduction box, main shaft fluid motor, two stature side cylinders etc.Reduction box is fixed on the platform.The main shaft fluid motor is installed on the reduction box.Side cylinder is installed in the main shaft both sides, and with unload discount and link to each other.Main shaft is set upright by spindle carrier and reduction box support.The shackle head part is installed in the front of main shaft, according to the kind difference of shackle thread protector, is divided into public thread protector shackle head part and female thread protector shackle head part.Public thread protector shackle head part is unloaded discount and public affairs mounted thereto by public thread protector and is unloaded the discount claw and constitute.Female thread protector shackle head part is unloaded discount by female thread protector and is constituted with the elastic slide block that is installed on it.Thread protector unloads the structure that discount adopts interior overcoat, and public affairs unload the discount claw or elastic slide block is installed in outer putting.When tubing thread protector of the present utility model unloads deduction work, be in the discount that unloads of retracted mode, under the promotion of drive part, after the body end, side cylinder by both sides is released it, unload special thread form and female effect of unloading the anterior elastic slide block of discount of discount claw by public affairs, the pre-chucking between discount overcoat and the thread protector is unloaded in realization, cause when unloading the discount rotation, relatively rotating between the overcoat in it, cover is released the inclined-plane tensioner and is put three claws that rotate around dead axle outward in making, thereby catches thread protector.
Tubing thread protector of the present utility model unloads deduction compared with prior art, has following effect and advantage:
1, realizes the mechanized of tubing end thread thread protector dismounting, alleviated working strength of workers, improved operating efficiency.
2, unloading discount can change easily, can adapt to the dismounting of the pin thread thread protector and the box thread protector of various different tubing different sizes.
3, running part has adopted hydraulic drive and pneumatic actuator, and is safe and reliable in the use.
Accompanying drawing 1 is the structural representation that public thread protector unloads deduction
Accompanying drawing 2 is structural representations that female thread protector unloads deduction
Below in conjunction with accompanying drawing 1 and accompanying drawing 2 given embodiment the utility model is further described:
Tubing thread protector among the embodiment unloads deduction and is unloaded discount 3,16 (dividing the male and female thread protector to unload discount), pre-gripping part 4,15 (the branch public affairs are unloaded discount claw and elastic slide block), a side cylinder 5, main shaft 6, reduction box 7, main shaft fluid motor 8, sliding platform 9, platform slideway 10, leading screw 11, leading screw fluid motor 12, base 13 etc. and formed by body 1, thread protector 2,14 (branch male and female thread protector), thread protector.The course of work of this machine is: body 1 unloads discount 3 or 16 and is in retracted mode earlier after being positioned and tightening, and drives leading screws 11 by fluid motor 12 and drives platforms 9 to front slide, makes 3 or 16 near public thread protector 2 or female thread protectors 14, is released 3 or 16 by a side cylinder 5 again.The claw 4 that public thread protector unloads discount has certain gradient with the shuttle thread that contacts of thread protector, and claw 4 not exclusively enters the thread protector inner ring, but is stuck on the thread protector inner peripheral surface with oblique shuttle thread, makes the certain frictional force of generation between claw 4 and the thread protector 2.Mother unloads and is enclosed within after discount 16 is pushed out on female thread protector 14, and its anterior elastic slide block 15 produces frictional force attached on thread protector 14 external surfaces.Main shaft fluid motor 8 drives when unloading the discount rotation by main shaft 6 because 4 or 15 and thread protector between the effect of frictional force, make to unload between the inside and outside cover of discount to produce relative rotation, interior cover is released inclined-plane tensioner claw, thereby thread protector promptly.After unloading discount and beginning rotation, a side cylinder 5 commutation drives and unloads discount and thread protector moves backward.After thread protector and body broke away from, rotation stopped, and moves behind the platform 9, finishes a course of work.
Claims (2)
1, a kind ofly is used for the tubing thread protector that the end is threaded and protects the tubing of the thread protector of screw thread, especially oil to go into the well casing material and unloads deduction, be made up of base portion, drive part, sliding platform part, main shaft portion and shackle part etc., it is characterized in that: base portion is made up of base (13) and platform slideway (10) fixed thereon; Drive part is by driving leading screw (11) and providing the leading screw fluid motor (12) of power to form to it; The sliding platform part is made up of platform (9) and spindle carrier and sliding nut fixed thereon; Main shaft portion is formed by main shaft (6), for its two stature side cylinders (5) that main shaft fluid motor (8), reduction box (7) of power are provided and are installed in main shaft (6) both sides; The shackle part is made up of the pre-gripping part that unloads discount and be installed on it.
